ABSTRACT:
Since its initial description as a safe and feasible access route for cardiac catheterization, the radial artery has been increasingly used for percutaneous coronary procedures. The transradial approach for percutaneous coronary procedures has the advantage of reduced adverse vascular events. Nevertheless, there are chances of transradial procedure failure due to variation in radial artery anatomy. We report a case of high radial artery origin in a 63 year-old-male patient who was taken up for elective radial percutaneous transluminal coronary angioplasty for in-stent restenosis of proximal left anterior descending artery. Subsequently, there was difficulty in negotiating guide wire and balloons, so imaging of radial artery was carried out which clearly demonstrated a high bifurcating radial origin. This case emphasizes the need for imaging of radial artery to delineate underlying anomalies and identifying patients with unfavorable anatomy when technical difficulties are encountered. Imaging in such a situation helps in planning an appropriate strategy.
